System variables
Current coupling status following spindle
The current coupling status of the following spindle
can be read in the NC part program with the
following axial system variable:
$AA_COUP_ACT[FS]
FS = axis name of the following spindle with spindle
number, e.g. S2.
The value which is read has the following meaning
for the following spindle:
0: No coupling active
4: synchronized spindle coupling active
Current angular offset
The setpoint of the current position offset of the FS
to the LS can be read in the part program with the
following axial system variable:
$AA_COUP_OFFS[S2]
The actual value for the current position offset can
be read with:
$VA_COUP_OFFS[S2]
FS = axis name of the following spindle with spindle
number, e.g. S2.
When the controller has been disabled and
subsequently re-enabled during active coupling and
follow-up mode, the position offset when the
controller is re-enabled is different to the original
programmed value. In this case, the new position
offset can be read and, if necessary, corrected in the
NC part program.
